Hey guys, this may be a dumb question but I'm gonna ask it anyways and embrace the laughter that is in my direction...

I have a 99' Integra GS-R. I live and deal with NJ inspections every two years and I also have a growing need to tune my car and make it faster. After reading things between forced induction and NA tuning, I've decided that NA is the way to go. Now to my question. I obviously want to get JDM headers with the 2.5 inch collector, I would also then want to get a cat that would bolt up to it in keeping with the 2.5 inch diameter all the way to my exhaust tip. Is it possible, or is there any aftermarket cat that actually works so I can meet emmissions in NJ while having 2.5 inches all the way to my exhaust tip??? Let me know, thankx

 

NEVER!!!!!!! NA's don't care about Smog Legal, thats the least of their worries. Just build that bad bitch up and hit up some people on the street

 

So I'm going to have to go with a greddy turbo then to keep my car street legal?

 

do they do smog checks in youre are?if not then dont sweet it run watever..

 

yea, the bitches in NJ hook up a hose to the exhaust tip and measure the output levels of chemicals... bastards...

So is there no way of going NA with 2.5in headers to a 2.5in cat and be street legal???

 

i believe carsound makes a 2.5 in cat. might wanna check them out

 

99 ?? they should be checking the ob2 sensor on the right side of your center panel - not the hose deal thats for obd1 - carsound has the cat ur lookin for
